Magnetic compression anastomosis can compress tissues together and restore the continuity. Magnetic compression anastomosis mainly experienced three stages: magnetic ring, magnetic ring and column, and smart self-assembling magnets for endoscopy (SAMSEN). Nowadays, the magnetic compression anastomosis has been applied in vascular and different digestive tract surgeries, especially for complex surgery, such as anastomotic stenosis of biliary ducts after liver transplantation or congenital esophageal stenosis. Although only case reports are available at present, the advantages of the magnetic compression anastomosis includes lower cost, simplicity, individualization, good efficacy, safety, and minimally invasiveness. We are building a better technical platform to make magnetic compression anastomosis more advanced and popularized.

OBJECTIVETo give a conceptual description of natural orifice translumenal endoscopic surgery (NOTES), review the early efforts in the NOTES field, and discuss its challenges and limitations.

DATA SOURCESThe data were retrieved mainly from publications listed in MEDLINE, PubMed and China Wanfang Database from 2005 to 2009. The search term was "NOTES".

STUDY SELECTIONThe articles involved in the "NOTES" study were selected and the review articles were excluded from the comparison.

RESULTSA marked increase in quantity in articles was shown each year for NOTES studies from 2006 to 2009. Animal experiments with "NOTES" have been carried out in China from 2007, and two independent "NOTES" procedures on humans were reported in 2009.

CONCLUSIONAlthough still in its infancy, the "NOTES" procedure is promising as another type of minimally invasive surgery and favorable alternative to current interventions.

Robotic system helps surgeons in performing surgery. Currently Da Vinci system is the most popular. Da Vinci system has been used for the stomach and bowel diseases in 27 cases(18 cases of stomach and 9 cases of colon and rectum) in the Zhongshan Hospital, Fudan University. Accurate preoperative staging is crucial, and Da Vinci system is advantageous in lymph node dissection, preservation of nerve plexus, and complete resection of mesorectum. Adoption of gastrointestinal tract reconstruction technique should depend on the operation and experience in surgery. Though Da Vinci system has limitations and the cost is high, it is believed to be the future trend.

With process optimization and technical innovation, laparoscopic gastrointestinal surgery has evolved dramatically over the last two decades and provided important improvement in the contemporary surgical practice and patients' recovery. With the emergence of many new minimally invasive technologies, including total laparoscopic surgery, single-incision laparoscopic surgery, and natural orifice specimen extraction, patents with gastrointestinal carcinomas may experience less pain and have lower perioperative complications, but the exact efficacy remains to be proven. Large-scale international multi-centre randomized controlled trial data have revealed that laparoscopic colorectal surgery is safe both in terms of short-term perioperative outcomes and long-term oncological efficacy. However, the question whether there is an equivalent oncological outcome compared to the open approach in gastric cancer is still unanswered by now and needs to be proven by future studies.

Nutritional risk and malnutrition was significantly higher in patients undergoing gastrointestinal surgery as compared to patients in other surgical departments, especially in elder patients, which would directly impact on the efficacy, cost and prognosis. Nutritional screening and assessment should be performed within 24-48 hours after admission. Patients at high risk of malnutrition should be planned with early nutrition support. The best nutrition route should be determined to improve the outcomes of surgery and nutritional support, reduce the complications, length of hospital stay and healthcare costs, and improve the quality of life in patients.

In recent years, laparoscopic total gastrectomy is gradually increasing for gastric cancer. Digestive tract reconstruction after laparoscopic total gastrectomy is one of the difficult problems for laparoscopic surgeons and the keys to success. Therefore, exploring an ideal method of digestive tract reconstruction is an important subject for clinical treatment. Reasonable choice and techniques of digestive tract reconstruction after laparoscopic total gastrectomy are summarized and evaluated in this article.
